Why do Apostolics have power with God?
We have power because we do those things which the New Testament says will bring Christians power.
Holy Ghost – At the end of Jesus’ ministry, He instructed His Apostles to go to Jerusalem and receive the “power from on high,” the Holy Ghost. In Acts 1:8 – Jesus explained to His Apostles, just prior to His ascension to heaven: “… ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me...

The word Apostle means “sent.” Jesus sent His Apostles into the world with a message. Jesus will not send someone else with a differing message. To do so would be confusing. God is not the author of confusion.
